Barking at the hardest tree ?
No the title is right....
I've just done some reading at Melabs about Longs in the recent versions of PBP and how they work with 18F series PIC's. I now think I may be doing sensor this the hard way with trying to use a 12F or 16F PIC.
A broad question: If the math involved in using this sensor only uses Longs and no floating point, can I use a 18FXXXX PIC to crunch the signed math, or is there a likely newbie Longs trap to fall into ?
I'd copy/paste the data sheets equations here to show you, but it's copy/paste protected. I'll attach it as a file.
It's only the last conversion from pressure to altitude that seems to use a float, and I can worry about that when I get that far (I hope). Page 12 is the guts of it.
